The lithium battery for your Bailey motorhome.

Bailey of Bristol has been making leisure vehicles since 1948 and currently runs a deliberately varied lineup. The Adamo and Alora are wide- and narrow-body coachbuilts on the Ford Transit, sized and specified for touring families who care about payload. The Autograph is Bailey's flagship coachbuilt and sits on a Peugeot Boxer with an AL-KO AMC chassis - a very different package to the Ford-based models, with a heavier GVWR on the upper variants. The Endeavour and Endurance are compact Ford Transit campervans: vans converted rather than coachbuilt. All of them keep the leisure battery under a front cab seat - passenger side on the Fords, driver's side on the Boxer-based Autograph.

That spread matters when you are choosing a battery. Battery location, space, payload headroom and charging architecture all vary by model. The good news is that TITAN's flat DIN case was designed precisely for the tight lockers and trays that UK motorhome and campervan builders work with, so a properly measured upgrade is straightforward across the whole Bailey range.

For the base vehicle context, see the Ford Transit guide (Adamo, Alora, Endeavour, Endurance) and the Peugeot Boxer guide (Autograph). The wider picture for motorhome brands and the motorhome battery hub cover the full context.

Every current Bailey keeps the leisure battery in the cab, under one of the front seats. Which seat depends on the base vehicle: Ford-based models use the passenger side, the Peugeot-based Autograph the driver's side. What changes between models is the height available under the seat frame and the payload headroom around it:

• Adamo and Alora - under the passenger cab seat. Both coachbuilts sit on the Ford Transit and carry the leisure battery in the void beneath the front passenger seat, the same place as every Ford-based Bailey. Height is the constraint, not footprint: measure from the seat-base floor to the frame above, and allow for the terminals and cable lugs on top of the case, before ordering. The flat DIN profile with low-set terminals was designed for this space. Swivel bases eat into the clearance on some Transit configurations, so check yours. The Adamo XL runs at 4,250 kg, which gives more payload headroom; the standard 3,500 kg Adamo and the lightweight Alora are more sensitive, so every kilogram matters.
• Autograph - under the driver's cab seat. The Autograph is built on the Peugeot Boxer, and the Boxer, Ducato and Relay family conventionally puts the leisure battery under the driver's seat rather than the passenger's. The same height rule applies: measure floor to frame, terminals included. The heavier 4,500 kg variants have the payload to carry a larger single lithium, and swapping a lead-acid pair for one lighter pack frees room for a charger, DC-DC unit and fusing alongside.
• Endeavour - under the passenger cab seat. As a Ford Transit panel van conversion, the Endeavour follows the standard van-conversion layout with the leisure battery under the cab seat. The DIN case suits this well, with low-profile terminals to help clear the seat frame above. Swivel bases on some Ford Transit configurations are tight, so measure before assuming.
• Endurance - twin under cab seats. The Endurance runs two 80Ah AGM batteries across both cab seats. Converting to a single lithium gives you equivalent or better usable capacity in one lighter, simpler pack, freeing the other seat void for storage or a charger.

In all cases, confirm your exact available space - including height with terminals in place - before ordering. Tray dimensions vary by model year and trim level, and the figure from a brochure is not always the same as what your specific van has.
